Mine is a Frigidaire 6000 series [affinity], but while searching for a cure it appears that they all suffer from the same flaw.
We've had ours for a couple years now & yesterday I got an E20 error & it wasn't draining. E20 isn't in the manual so I googled and found this thread-
Then they bury it in the damn machine! [I wanted to capitalize that and use 40 exclamation points but I'm tired]
Here's the process to get to mine; Take out soap tray.
2 screws on back of top- and slide back.
5 screws & 3 clips on console, and fold out of way. pull spring clip off boot and release boot.
8 screws to loosen front panel
2 screws on door latch- and a clip to release wires.
Then the hose clamps- one screw and one spring- to open the drain hose.
I did it myself in 1 hour- but many folks would be paying a plumber for a job they should be able to do in 10 minutes.
Anybody want a nice 2yr old Affinity set in almond?
Jim BTW- I had $2.91, an earring and 2 color catchers in mine.
